Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with high death rates. Aucubin is an iridoid glycoside extracted from Eucommia ulmoides with antioxidative and anti-inflammatory properties in human diseases. This study aimed to investigate its specific function in mouse and cell models of COPD. METHODS The COPD mouse model was established by exposing mice to a long-term cigarette smoke (CS). The number of inflammatory cells and the contents of inflammatory factors tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6), and IL-8 in bronchoalveolar lavage fluid (BALF) of CS-exposed mice were measured. The levels of superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and myeloperoxidase (MPO) in the lung tissues were estimated. Masson staining and hematoxylin-eosin (H&E) staining were utilized to evaluate pulmonary fibrosis and emphysema in CS-treated mice. Cell apoptosis in the lung tissues was estimated by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Western blot was applied to quantify protein levels of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and apoptotic markers. COPD cell model was established by exposing mouse lung epithelial cells (MLE12) with cigarette smoke extract to further verify the properties of aucubin in vitro. RESULTS Aucubin reduced the number of inflammatory cells and decreased the contents of TNF-α, IL-6, and IL-8 in BALF of CS-treated mice. The oxidative stress, lung emphysema, fibrosis, and lung cell apoptosis induced by CS exposure were ameliorated by aucubin administration. Aucubin activated the Nrf2/HO-1 signaling pathway in vitro and in vivo. Pretreatment with ML385, a specific Nrf2 inhibitor, antagonized the protective effects of aucubin on inflammation, oxidative stress, fibrosis, and cell apoptosis in COPD. CONCLUSION Aucubin alleviates inflammation, oxidative stress, apoptosis, and pulmonary fibrosis in COPD mice and CSE-treated MLE12 cells by activating the Nrf2/HO-1 signaling pathway.

Abstract
Gastritis, one of the most common gastrointestinal disorders, damages the stomach lining as it causes a disproportion between the protective and ruinous factors of the gastric system. Cabbage (CB) is widely used to treat gastric lesions but requires the addition of natural sweeteners to counteract its distinct bitter taste. Therefore, this study sought to determine whether the combination of chestnut honey (CH)-which is known for its dark brown color and high kynurenic acid (KA) content-or KA-increased CH (KACH) with CB (CH + CB or KACH + CB) exerts synergistic effects for improving both taste and efficacy. Before confirming the gastroprotective effects in indomethacin (INDO)-induced rats, the anti-inflammatory activities of CH + CB and KACH + CB were assessed in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. As a result, treatment with either CH + CB or KACH + CB downregulated pro-inflammatory cytokine levels in LPS-stimulated RAW 264.7 macrophages by regulating the translocation of nuclear factor kappa B. Furthermore, both CH + CB and KACH + CB not only enhanced the levels of antioxidant enzymes but also triggered the activation of nuclear factor erythroid-related factor 2. Based on these effects, CH + CB or KACH + CB effectively protected the gastric mucosa in INDO-induced rats. Therefore, this study suggests that CH + CB and KACH + CB exert stronger gastroprotective effects when used together.

Abstract
One of the top ten tonic herbs, Dangshen is frequently found in Chinese functional foods. With the inclusion of Dangshen in the list of food and medicine substances in 2020, the Dangshen Huangjiu (DHJ) emerged. In the Bencao, it is written that Huangjiu can "open up the curved veins and thicken the stomach and intestines". Furthermore, increasing investigations have verified the protective effect of Dangshen on the gastric mucosa. Therefore, we propose the hypothesis that the stomach mucosa might be protected by the DHJ. To demonstrate that the effect of solids in Dangshen Huangjiu (DHJG) on damaged human gastric mucosal epithelial cells (GES-1) was reversed, the study used ethanol to induce injury to GES-1 and then used protein immunoblotting (western blotting) to determine the expression levels of p-Akt, p-NF-κB-p65, and NF-κB-p65 proteins in the cells. 0.04 mol L-1 MNNG (5 mL kg-1 body weight) mixed with eating disorders(2 d satiety, l d starvation, 3 d cycle) was used to further establish a chronic non-atrophic gastritis (CNAG) model in Wistar rats, at the same time, the experimental rats were given DHJ and DHJG gavage. Cellular assays confirmed that DHJG (25-100 μg mL-1) dose-dependently increased the viability of ethanol-injured GES-1 and lowered p-Akt and p-NF-κB-p65/NF-κB-p65 protein expression. Animal experiments revealed that 10 mL kg-1 and 20 mL kg-1 DHJ had no significant effect on the basic activity and gastric tissues and related biochemical indices of healthy rats; DHJ (10 mL kg-1, 20 mL kg-1) and DHJG (2.8 g kg-1, 11.4 g kg-1) resulted in some improvement in weight loss and significant improvement in gastric mucosal pathology in CNAG rats with damage. Particularly, DHJ and DHJG significantly decreased the expression of p-Akt, p-NF-κB-p65/NF-κB-p65 and Bcl-2/Bax proteins and Akt, IKKβ, IκBα and NF-κB mRNA in the gastric tissues of CNAG rats. These results showed that DHJG ameliorates ethanol-induced GES-1 cell injury; both DHJ and DHJG alleviate CNAG, and the mechanisms by which they do so may be related to DHJ and DHJG increasing the antioxidant capacity (elevating SOD, decreasing MDA), attenuating inflammatory responses (decreasing IL-1β, IL-6, and TNF-α), reversing apoptosis (reducing the Bcl-2/Bax ratio) and down-regulating gastric tissue p-Akt and p-NF-κB-p65/NF-κB-p65 protein expression as well as Akt, IKKβ, IκBα and NF-κB mRNA expression. This study indicates that the interventional effects of DHJ and DHJG in CNAG may act through the Akt/NF-κB signaling pathway.

Abstract
Finger citron pickled products (FCPP), as folk remedies, are famous in southern China for protecting gastric mucosa. However, the gastric mucosa protection of FCPP has not been reported yet, and its effective mechanism is unclear. In this study, the protective mechanism of FCPP aqueous extract on gastric mucosa was investigated in vitro and in vivo for the first time, using human gastric mucosa epithelial cells (GES-1) and acute alcoholic gastric ulcer rat model respectively. Furthermore, we also investigated the main substances in the aqueous extract that exert gastroprotective activity using a GES-1 scratch test and basic chemical composition analysis. FCPP aqueous extract was found to play a protective and reparative role in GES-1 by promoting the secretion of trefoil factor thyroid transcription factor 2 (TFF2) and inhibiting the secretion of tumor necrosis factor-α (TNF-α) in cells damaged by alcohol. The ulcer index of gastric tissue induced by alcohol was significantly decreased (p < 0.01) after pretreatment with FCPP aqueous extract, indicating that FCPP aqueous extract had a good protective effect on the stomach mucosa. Moreover, FCPP aqueous extract could increase superoxide dismutase (SOD) activity and inhibit malondialdehyde (MDA) content, exhibiting good antioxidant capacity. Aqueous extract of FCPP could also effectively inhibit the increase of cytokines TNF-α, interleukin-1β (IL-1β) and interleukin-6 (IL-6) in serum of rats, and promote the increase of anti-inflammatory cytokines interleukin-10 (IL-10) to some extent. Furthermore, FCPP aqueous extract could inhibit the expression of nuclear factor kappa-B (NF-κB/P65) protein, caspase-1 protein and IL-1β protein in the gastric tissue of rats, while promoting the expression of IκBα protein, indicating that the gastric mucosa protection effects of FCPP aqueous extract were mainly dependent on the NF-κB/caspase-1/IL-1β axis. The polysaccharides in FCPP aqueous extract might be the main components that exerted gastroprotective activity, as demonstrated by GES-1 cell scratch assay. This study confirmed that FCPP aqueous extract presented promising potential in protecting gastric mucosa and avoiding gastric ulcers, which could provide an experimental basis for further utilizing the medicinal value and developing new products of FCPP.

Abstract
Aucubin is an iridoid glycoside widely spread in the families Cornaceae, Garryaceae, Orobanchaceae, Globulariaceae, Eucommiaceae, Scrophulariaceae, Plantaginaceae, and Rubiaceae. This review is intended to provide data on the physicochemical characteristics, isolation methods, and biological activities of aucubin and its producing plants. Aucubin is unstable and can be deglycosylated into its aglycone, aucubigenin. Various chromatographic methods (column chromatography, vacuum liquid chromatography, medium pressure liquid chromatography, and high-performance liquid chromatography) have been used together to isolate aucubin, mainly with the stationary phase C-18 and the mobile phase water-methanol solution made in gradients. In vitro and in vivo studies reveal that aucubin has a wide range of activities, including anti-inflammatory, antioxidant, anxiolytic and antidepressant, antidiabetic, antifibrotic, antimicrobial, anticancer, antihyperlipidemic, gastroprotective, cardioprotective, hepatoprotective, retinoprotective, neuroprotective, osteoprotective, and renoprotective. Even though aucubin has been extensively investigated, further research in humans is urgently needed primarily to substantiate the clinical evidence. Moreover, extensive studies on its drug delivery systems will help maximize efficacy and minimize side effects.

Abstract
Gastric ulcer is a common gastrointestinal ailment that affects many people worldwide. NSAIDs induced ulcers are the second most common etiology of gastric ulcers. Coconut oil has well-known potential anti-ulcerogenic characteristics. This work aimed to develop and optimize diclofenac potassium (a highly used model drug of NSAIDs) as self-nanoemulsifying delivery system containing coconut oil (DFP-COSNEDS) to overcome its ulcerogenic effect. A mixture design was applied for formula optimization and investigation of the effect of different formulation factors on the droplet size (DS) and polydispersity index (PDI) of the prepared DFP-COSNEDS. The optimized formulae showed good self-emulsification characters and better drug dissolution compared with the drug suspension. The ulcer protection was assessed in-vivo using 7 groups of adult male Wistar rats. Oxidative stress parameters (MDA, GSH, and SOD), inflammatory mediators (PGE-2, TNF-α, and IL-6) and peroxisome proliferator-activated receptor-γ (PPAR-γ) gene expression were measured. The results revealed that pure coconut oil and DFP-COSNEDS containing 25 % of coconut oil showed close figures to normal group and better values than famotidine (FAM) group. In conclusion, coconut oil showed high potential for gastric-protection activity against DFP induced ulcer. DFP-COSNEDS offers dual benefits of improving DFP dissolution and alleviating its ulcerogenic effect.

Abstract
BACKGROUND Gastric mucosal injury caused by ethanol is a common gastrointestinal disease. Quinoa (Chenopodium quinoa Willd.), as a nutrient-rich grain, plays a significant role in preventing and treating gastric mucosal damage. The present study aimed to explore the protective effect of quinoa on alcohol-induced gastric mucosal damage and its possible mechanism. RESULTS The ethanol-induced gastric mucosal injury rat model was used for in vivo experiments and H2 O2 -induced GES-1 cells for in vitro experiments to elucidate the protective effect of quinoa. The results show that quinoa water extract can increase the superoxide dismutase level and decrease the malondialdehyde level in vitro and in vivo. Furthermore, quinoa also reduced the bleeding point and bleeding area in rats with ethanol-induced gastric mucosal injury and improved gastric histopathological changes. H2 O2 significantly increased the levels of inflammatory factors in GES-1 cells, which were markedly ameliorated by quinoa water extract. Likewise, quinoa water extract regulated the protein expression levels of Nrf2, Keap1, HO-1, p-IKK, and p-NF-κB through Nrf2 and nuclear factor-κB signaling pathways, reducing the production of oxidative stress and inflammation, thereby repairing the damaged gastric mucosa. CONCLUSION The findings of this study demonstrated that quinoa shows protective effect against ethanol-induced gastric mucosal injury through its anti-inflammatory and anti-oxidant effects. We propose that our research will provide a reference for quinoa as a functional food. © 2022 Society of Chemical Industry.

Abstract
OBJECTIVE Helicobacter pylori is planted in the human stomach and is the most common cause of chronic gastritis, which produced specific local and systemic humoral immunity, while the associations of these immune responses and H. pylori in the development of chronic gastritis remain unclear. METHODS This study analyzed histology, the number of Th22 and regulatory T (Treg) cells, and the levels of inflammation- and gastritis-related indicators between 22 H. pylori-infected and 24 non-H. pylori-infected chronic gastritis patients by hematoxylin-eosin staining, enzyme-linked immunosorbent assay, quantitative reverse transcription PCR, and flow cytometry analysis. RESULTS This study found that the pathological damage degree of gastric mucosa in H. pylori infection patients was more serious. In the H. pylori-infected patient serum, the gastrin, G-17, interleukins (IL)-22, transforming growth factor (TGF)-β, tumor necrosis factor (TNF)-α, IL-4, and IL-17A levels were notably raised, while the interferon (IFN)-γ level was inhibited, and in gastric mucosa, and except IFN-γ, the IL-22, forkhead box P3 (Foxp3), TNF-α, IL-4, and IL-17A mRNA levels were raised too. The receiver operating characteristic curve analysis indicates serum IL-22, TGF-β, TNF-α, IL-4, and IL-17A are suitable for differential diagnosis of H. pylori infection. In addition, in the peripheral blood, the percentages of the IL-22+ CD4+ and Foxp3+ CD4+ T cells were raised with H. pylori infection. The positive correlation between IL-22 and Foxp3 mRNA levels and the degree of H. pylori colonization and gastric mucositis by Pearson's correlation analysis. CONCLUSIONS Treg and Th22 cells were positively associated with the degree of H. pylori infection and the severity of gastritis. In summary, this study provides an experimental basis for the study of the eradication of H. pylori and the biological mechanism of chronic gastritis.

Abstract
Objective The present study aimed at the anti-inflammatory and antioxidant effects of the extract of Bruguiera gymnorrhiza (L.) Lam. fruit (BGF) on the gastric injury. Materials and Methods The chemical components in the extract of BGF were used in UPLC/Q-Orbitrap analysis. 60 SD rats were randomized into six groups: normal group (MC), ethanol-injured control group (EC), omeprazole group, and three groups with different doses (50, 100, and 200 mg/kg) of BGF. After continuous administration for seven days, the stomachs of rats were taken out to observe the pathological gastric tissue changes; inflammatory factors and oxidative stress markers in the stomach tissues were measured. Western blot (WB) analyses were conducted to explore the mechanism of BGF on gastric tissue and RAW 246.7 cells with excessive inflammation. Results BGF enhanced gastric mucosal protection by improving the mucosal blood flow of the stomach and significantly decreased inflammatory factors and oxidative stress markers. Moreover, BGF significantly reduced the expression of p-NF-κB p65. Consistently, BGF demonstrated similar effects on LPS-induced RAW 264.7 cells as it did in vivo. Conclusion BGF could accelerate the healing of gastric injury by exerting antioxidant and anti-inflammatory effects and maintaining mucosal integrity.

Abstract
Aucubin, a natural compound isolated from herbal medicine, has been reported to possess multiple beneficial properties. In this study, we aimed to verify the anticancer effect of aucubin on breast cancer and investigate the effect of cancer on the intestinal flora and whether aucubin has a therapeutic effect on intestinal problems caused by cancer. We established the breast cancer model with mouse 4T1 cell line and BALB/c mice. Aucubin was given once a day by gavage for 14 days. The results showed that aucubin suppress the growth of tumor in vivo by inducing tumor cell apoptosis. The tumor suppression rate of aucubin could reach 51.31 ± 4.07%. Organ histopathology was evaluated by tissue staining, which demonstrated that aucubin could alleviate the organ inflammatory damage caused by breast cancer without visible side effects. Moreover, aucubin could increase the expression of colonic tight junction protein occluding and adjust the gut microbiome to normal level according to 16S rDNA high-throughput sequencing. Herein, our results provide evidence for developing aucubin as an alternative and safe therapeutic for breast cancer treatment.

Abstract
Gastritis and gastric ulcers caused by stressors such as drinking are common. The ability of functional foods to protect the stomach more effectively and reduce the risk of side effects is of interest. The fermentation process can increase the preservation and bioactive compound content of kiwi fruits. This study produced fermented kiwi powder using two lactic acids separated from gold kiwi fruits. Gold kiwi puree (Actinidia chinensis L.) was fermented using beneficial bacteria. Fermentation increased the content of bioactive compounds such as organic acids, flavonoids, and carotenoids. We investigated whether fermented gold kiwi (FGK) extract had antioxidant and gastric protective effects in an HCl/EtOH-induced gastritis animal model and pyloric ligation animal model. FGK increased radical scavenging activity in a dose-dependent manner. In the gastritis model, FGK inhibited inflammation-related factors such as iNOS, COX-2, IL-6, and TNF-α, while increasing the expression of the protective molecule PGE2. Furthermore, FGK administration improved gastric lesion site appearance, clinical symptoms, and mucosal thickness in rats. FGK also reduced gastric fluid volume, free acidity, total acidity, and pepsin activity in the pyloric ligation model. These results suggest that FGK can decrease the inflammatory response and protect the gastric mucosa. FGK therefore has the potential to prevent and treat gastritis and gastric ulcers.

Protective Effect and Potential Mechanism of the Traditional Chinese Medicine Shaoyao-Gancao Decoction on Ethanol-Induced Gastric Ulcers in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:3069089. [PMID: 35449820 PMCID: PMC9017495 DOI: 10.1155/2022/3069089] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 02/27/2022] [Accepted: 03/30/2022] [Indexed: 11/17/2022]
Abstract
Background Shaoyao-Gancao decoction (SGD) is a classic prescription in traditional Chinese medicine. SGD is effective in the treatment of gastric and duodenal ulcers. However, the biological activity and possible mechanisms of SGD in the treatment of gastric ulcers have not been fully elucidated. The purpose of this study was to scientifically evaluate the protective effect and potential mechanism of SGD against ethanol-induced gastric ulcers in rats. Methods A single gavage of 10 mL/kg of 75% ethanol was used to establish a rat gastric ulcer model. A histopathological examination of the gastric tissue was performed. The levels of TNF-α, EGF, PGE2, SOD, and TBARS in gastric tissue were measured by ELISA. Cellular apoptosis in gastric tissues was assessed by TUNEL assay. The expression levels of caspase-3 and Bcl-2 were determined by immunohistochemistry. The potential mechanism of SGD in treating gastric ulcers was further studied using a network pharmacology research method. Results The gastric tissue of rats with ethanol-induced gastric ulcers had obvious injury throughout the mucosal layer, which was significantly weakened in rats treated with SGD. Furthermore, treatment with SGD significantly increased the levels of EGF, PGE2, SOD, and Bcl-2 and decreased the levels of TNF-α, TBARS, and caspase-3 in the gastric tissue of rats with ethanol-induced gastric ulcers. SGD reduced ethanol-induced cell apoptosis in gastric tissue from rats with gastric ulcers. A traditional Chinese medicine-based network pharmacology study revealed that SGD exerts its anti-gastric ulcer effect by acting on multiple pathways. Conclusions The above results indicate that SGD can improve gastric ulcers induced by ethanol. Moreover, this study demonstrated multicomponent, multitarget, and multipathway characteristics of SGD in the treatment of gastric ulcers and provided a foundation for further drug development research.

Abstract
This study was designed to evaluate the gastroprotective activity of cirsilineol in hydrochloric acid (HCl)/ethanol-induced gastric ulcer model. Cirsilineol was administered at the doses of 20 and 40 mg/kg in HCl/ethanol-induced rats. The gastroprotective ability was verified by determining the ulcer score, total acidity, hemoglobin, inflammatory cytokines, lipid peroxides, and enzymatic antioxidants superoxide dismutase (SOD) and catalase (CAT) in gastric tissue and serum biochemical analysis. The results showed a favorable increase in the hemoglobin level, antioxidant enzymes (SOD and CAT), restored electrochemical balance (carbon dioxide & anion gap) while a noticeable decrease in ulcer index, total acidity, lipid peroxides, inflammatory cytokines (interleukin-1 beta [IL-1β], IL-6, and tumor necrosis factor alpha) in rats treated with the cirsilineol. The serum biochemical analysis on liver markers (alkaline phosphatases, alanine aminotransferase, and aspartate aminotransferase), kidney markers (urea, creatinine, albumin, globulin, total protein), and lipid profile (triglyceride, high-density lipoprotein, total cholesterol) were attenuated by cirsilineol treatment in rats. Histopathology showed enhanced gastric protection and preserved the integrity of gastric mucosa upon cirsilineol administration. These results ultimately suggest that cirsilineol has gastroprotective effects that prevent the development of gastric ulcer.

Abstract
Gastric mucosal injury is caused by an imbalance between the mucosal defense and gastro-irritants, leading to gastroenteritis. Diosgenin is a steroidal sapogenin found in the wild Yam plant that has been reported with several pharmacological properties. The aim of this study is to explore the gastroprotective role of diosgenin on gastric mucosal damage caused by HCl/ethanol in rats. Male Sprague-Dawley rats were intragastrically administered with diosgenin (20 mg/kg) before HCl/ethanol (0.15 M HCl in 98 % ethanol) administration. Omeprazole was used as a positive control. Diosgenin-attenuated oxidative stress by enhancing (p < 0.05) antioxidant enzymes, reducing lipid peroxidation (MDA), and modulating nitric oxide (NO) levels. Anti-inflammatory effects of diosgenin were observed by a reduction in pro-inflammatory cytokines (p < 0.05), decreased myeloperoxidase (MPO) activities (p < 0.05), and histopathological observation of gastric mucosal damage. Western blot analysis provided evidence on the downregulation of NF-κβ by diosgenin. The findings showed that diosgenin has a significant protective role on gastric injury caused by HCl/ethanol, through its antioxidant, anti-inflammatory role, and suppression of NF-κβ and MPO activities.

Abstract
Nowadays, consumers have an increasing demand for health products. In this study, an oral liquid was developed using a compound extract consisting of three herbal extracts (Dendrobium nobile Lindl., Lycium barbarum, and Puerariae lobatae Radix) because the compound extract (a combination of all three extracts) was superior to every single extract in promoting the phagocytic capacity of RAW264.7 macrophages and the proliferation ability of GES-1 cells. In this oral liquid, the dosage of the stabilizer and the sweetener was selected using a stability test and sensory quality evaluation. When 0.30% (m/v) xanthan gum and 0.20% (m/v) mogroside were added, the oral liquid had not only a good stability but also the highest sensory score for overall acceptability. The chemical composition analysis showed that the oral liquid had various functional ingredients including polysaccharides, phenols, alkaloids, and so forth. The immune-enhancing efficacy of the oral liquid was evaluated in BALB/c mice by measuring the levels of different immune indicators. The results indicated that the oral liquid obviously enhanced nonspecific and specific immunity. A rat model with ethanol-induced gastric ulcer was used to examine the protective effect of the oral liquid on the gastric mucosa and to explore the related mechanisms. The oral administration of the oral liquid for days significantly prevented the formation of gastric ulcer. This study provided an effective oral liquid that could enhance immunity and protect gastric mucosa.

Abstract
The aim of this work was to evaluate the gastroprotective activity of a Mexican propolis on indomethacin-induced gastric ulcers in a mouse model. The following contents of the ethanolic extract of propolis of Chihuahua (EEPCh) were determined: antioxidant activity (SA50), total phenolic content (TPC), total flavonoid content (TFC), and chemical composition by HPLC-DAD and HPLC-MS, as well as acute toxicity by OECD Guideline 423. Gastric lesions were induced by intragastric indomethacin treatment in male ICR mice. As the positive control, omeprazole was administered, and three doses of EEPCh were evaluated (50, 150 and 300 mg/kg). Gastric mucosal injury, histological changes and mucosal content were evaluated by means of H&E and PAS staining. For homogenized gastric tissues, the following were evaluated: TBARS, MPO, and PGE2 levels; SOD and GPx antioxidant enzymatic activity; and the concentrations of the proinflammatory cytokines, TNF-α, IL-1β and IL-6. EEPCh had a significant SA50 of 41.55 µg/mL. The TPC of EEPCh was 860 mg GAE/g, and its TFC was 49.58 mg QE/g. Different phenolic compounds were identified in the extract and were not toxic. The EEPCh doses decreased mucosal damage and histological injuries, maintained the mucosal content and reduced the TBARS, MPO and concentrations of proinflammatory cytokines in gastric ulcer tissues. The 150 and 300 mg/kg doses increased the SOD activity and maintained the PGE2 content. Only the 300 mg/kg dose increased the GPx activity. The results of this study suggest that EEPCh displays gastroprotective effects by means of its antioxidant activity and anti-inflammatory effects and promotes ulcer protection through the maintenance of mucosal content and PGE2 levels.

Abstract
The protective effect of Lactobacillus plantarum HFY09 (LP-HFY09) on alcohol-induced gastric ulcers was investigated. Gastric morphology observation and pathological tissue sections showed that LP-HFY09 effectively relieved gastric tissue injury. The biochemical indicator detection showed that LP-HFY09 increased superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH), prostaglandin E2 (PGE2), and somatostatin (SS) levels, and decreased malondialdehyde (MDA) levels. Moreover, LP-HFY09 inhibited the levels of inflammatory cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α), and elevated the level of anti-inflammatory cytokine IL-10. The quantitative polymerase chain reaction (q-PCR) examination revealed that LP-HFY09 enhanced the mRNA expression of nuclear factor E2-related factor 2 (Nrf2) and downstream genes, including copper/zinc superoxide dismutase (SOD1), heme oxygenase-1 (HO-1), gamma-glutamylcysteine synthetase (GSH1), manganese superoxide dismutase (SOD2), catalase (CAT), and GSH-Px. This study indicated that LP-HFY09 alleviated alcohol-induced gastric ulcers by increasing gastric mucosa defense factor, and inhibiting oxidative stress and the inflammatory response. PRACTICAL APPLICATIONS: LP-HFY09 has the potential to be investigated as a treatment for gastric injury induced by alcohol.

Abstract
Pistacia atlantica Desf. (Atlas Pistachio) is an Anacardiaceae tree traditionally used in Tunisia for the treatment of ophthalmic, stomatitis, and digestive tract diseases. In the present study, the Pistacia atlantica Desf. roots extract (PR) was phytochemically analyzed, for the first time, by LC-ESI-MS for phenolic and flavonoid contents, in vitro tested for its potential antioxidant activity based on the 2.2-diphenyl-1-picrylhydrazyl (DPPH) and the reduced power essays (FRAP), and in vivo tested for its ability to shield against ethanol-induced gastric ulcer in mice. The LC-ESI-MS analysis proved the identification of 12 compounds, including Quinic, Gallic, and Protocatechuic, as major phenolic acids and high levels of flavonoids, such as Catechin, Epicatechin, and Cirsiliol. PR also exhibited a mild in vitro antioxidant activity when compared with ascorbic acid. In vivo pretreatment of ethanol-ulcerated mice with PR doses 50 mg/kg and 100 mg/kg body weight (b.w) significantly reduced (P< .05) gastric lesions at a rate of 20.10% and a rate of 40.90%, respectively, when compared with 60.70% rate of sucralfate (50 mg/kg b.w) evidenced by a dose-dependent manner increase in the gastric mucosa enzymatic (SOD, CAT, GPx) antioxidant levels, the decline of the lipid peroxidation, and the preservation of normal gastric superficial epithelium. The underlying mechanism of PR antiulcerogenic activity could be due to a synergistic effect of phenolic acids and flavonoid contents which enhances the gastric antioxidant defense system.Abbreviations: BHT: butylated hydroxytoluene, b.w: body weight, CAT: catalase, DPPH:1-Diphenyl-2-picrylhydrazyl, DW: dry weight, EtOH: ethanol, FRAP: Ferric reducing antioxidant power, GAE: gallic acid equivalents, GPx: Glutathione peroxidase, QE: quercetin equivalents, LC-ESI-MS: Liquid chromatography-Electrospray Ionization-Tandem Mass Spectrometry, MDA: malondialdehyde, PR: Pistacia root, TBA: thiobarbituric acid reagent, TBARS: thiobarbituric acid reactive substances, TCA: trichloroacetic acid, SOD: Superoxide dismutase.

Abstract
Gastric ulcers are a very common public health problem affecting up to 10% worldwide. Russelioside B is a steroidal glycoside isolated from several Caralluma species. No study tested the ulcer healing potential of the compound. The current study aimed to assess the protective effect of russelioside B against ethanol-induced gastric mucosal injury in rats. Ulcer was induced on rats by a single intragastric dose of absolute ethanol (5 mL/kg). Rats were randomly assorted into four groups (n = 8) and given treatments (Antodine, 20 mg/kg or russelioside B, 50 mg/kg) by oral gavage 1 h before ulcer induction. Pretreatment with russelioside B (50 mg/kg) attenuated the gastric mucosal injury as proved by a decrease of ulcer index, and histological scores. It suppressed the gastric inflammation by a significant lowering the tumor necrosis factor-α and interleukin-6 levels with myeloperoxidase activity (which are also aggravating factors in the case of Covid-19 infection). In addition, administration of russelioside B halted the gastric oxidative stress via inhibition of lipid peroxides by maintaining reduced glutathione and by decreasing malondialdehyde. It was able also to restore the sharp drop in the levels of heat shock protein-70, vascular endothelial growth factor and prostaglandin E2 induced by ethanol. Additionally, it showed carbonic anhydrase inhibition activity. The gastroprotective action of russelioside B was umpired through multi mechanistic actions; suppression of gastric oxidative stress, inflammation, anti-apoptotic activities and enhanced gastric mucosal protection by up-regulation of endothelial growth factor, normalization of heat shock protein-70 and prostaglandin E2. These actions were comparable in part to some classical antiulcer drugs such as Antodine.

Abstract
Ethanol-induced gastric mucosal injury is a common gastrointestinal disorder. Polysaccharides separated from herbs have been shown to be effective for ethanol-induced gastric mucosal injury, but whether the polysaccharides from Dendrobium officinale Kimura & Migo leaves (LDOP-1) protected mucosa from ethanol-induced injury remains unknown. Thus, the present study carried out gastric mucosal protection and the mechanism of LDOP-1 in vivo and vitro. The chemical composition of LDOP-1 was a heteropolysaccharide comprising mannose, galacturonic acid, glucose, galactose, and arabinose at a molar ratio of 2.0:1.1:0.7:0.5:0.4. Pharmacological results showed that LDOP-1 significantly reduced gastric mucosal injury score and pathological injury, improved antioxidant capacity, reduced the level of reactive oxygen species, and reversed the apoptosis of GES-1 in vivo and vitro. Research showed that LDOP-1 pretreatment upregulated the expression level of p-AMPK, LC3β, HO-1, and Beclin-1; downregulated the expression level of p-mTOR and p62; and reversed the expression level of caspase3, Bax, and Bcl-2. This study was the first to demonstrate that LDOP-1 could protect against ethanol-induced gastric mucosal injury via the AMPK/mTOR signaling pathway in vitro and vivo.

Nerolidol-beta-cyclodextrin inclusion complex enhances anti-inflammatory activity in arthritis model and improves gastric protection. Life Sci 2020; 265:118742.

Abstract
Rheumatoid arthritis is an autoimmune inflammatory disease with progressive degradation of cartilage and joints. Additionally, gastric ulcer affects many patients who make prolonged use of non-steroidal anti-inflammatory drugs widely used in the symptomatic treatment of rheumatoid arthritis. Nerolidol, a natural sesquiterpene, has several biological activities including anti-inflammatory and antiulcerogenic action. This study aims to develop and characterize a nerolidol ß-cyclodextrin inclusion complex and to evaluate its activity in an experimental arthritis model. Inclusion complex was prepared by the lyophilization method and characterized by NMR, term analysis, XRD and SEM. Neutrophil migration assays and histopathological analysis were performed on zymosan-induced arthritis model using Swiss mice. And the gastroprotective effect was evaluated in two models of gastric ulcers: induced by ethanol and indomethacin. Inclusion complex showed no cytotoxicity and free nerolidol at a dose of 100 mg/kg (p.o.) in the arthritis model reduced neutrophil migration in 56% in relation to vehicle, and this inhibition was more expressive in the inclusion complex (67%) at the same dose. Histopathological analysis of the joint tissue confirmed the reduction of inflammatory signs. In the ethanol-induced gastric ulcer model, free nerolidol reduced the relative ulcer area more expressively (4.64%) than the inclusion complex (21.3%). However, in the indomethacin induction model, the inclusion complex showed better results in gastric protection compared to free nerolidol. The action of nerolidol complexed in beta-cyclodextrin in reducing arthritis inflammation combined with its gastroprotective action make it a potential new drug.

Abstract
This study explored the role of the depressor arm of renin-angiotensin system (RAS) on ischemic renal injury (IRI)-associated cardio-hepatic sequalae under non-diabetic (ND) and diabetes mellitus (DM) conditions. Firstly, rats were injected with Streptozotocin (55 mg/kg i.p.) to develop DM. ND and DM rats underwent Bilateral IRI followed by 24 h of reperfusion. Further, ND and DM rats were subjected to AT2R agonist-Compound 21 (C21) (0.3 mg/kg/day, i.p.) or ACE2 activator- Diminazene Aceturate (Dize), (5 mg/kg/day, p.o.) per se or its combination therapy. As results, IRI caused cardio-hepatic injuries via altered oxidant/anti-oxidant levels, elevated inflammatory events, and altered protein expressions of ACE, ACE2, Ang II, Ang-(1-7) and urinary AGT. However, concomitant therapy of AT2R agonist and ACE2 activator exerts a protective effect in IRI-associated cardio-hepatic dysfunction as evidenced by inhibited oxidative stress, downregulated inflammation, and enhanced cardio-hepatic depressor arm of RAS under ND and DM conditions.

Abstract
The aim of the study was to investigate traditionally used Royal Jelly (RJ) for treating an ethanol-induced gastric ulcer model in rats. A total of 32 Wistar albino male rats were divided into 4 groups of 8: group I = Control, group II = Ethanol, group III = RJ + Ethanol, and group IV = Lansoprazole + Ethanol. In groups II, III, and IV, animals were administered 1 ml of absolute ethanol orally after a 24-h fast to induce ulcer formation. The histopathological changes in the gastric mucosa were determined using hematoxylin-eosin (H&E) staining. Immunohistochemically, inducible nitric oxide (iNOS) and nuclear factor kappa beta (Nf-κβ) markings were evaluated in gastric tissue. Cell death in the gastric mucosa was determined by the TUNEL method. Oxidative status markers, superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), and myeloperoxidase (MPO) levels were determined spectrophotometrically. Expression of the interleukin - 1 beta (IL-1β) and tumor necrosis factor-α (TNF-α) genes in gastric tissues was determined by real-time PCR; and TNF-α, IL-10, and IL-1β levels were determined. RJ was found to inhibit iNOS and Nf-κβ activity in the gastric mucosa and prevent epithelial cell apoptosis. In particular, pro-inflammatory cytokines TNF-α and IL-1β levels were significantly decreased in the RJ + Ethanol group compared to the Ethanol group. In addition, a decrease in the MPO level indicated that RJ prevented tissue damage, especially by preventing inflammatory cell infiltration. The study demonstrated a possible gastroprotective effect of RJ in a rat ethanol-induced gastric ulcer model.

Aucubin Attenuates Liver Ischemia-Reperfusion Injury by Inhibiting the HMGB1/TLR-4/NF-κB Signaling Pathway, Oxidative Stress, and Apoptosis. Front Pharmacol 2020; 11:544124. [PMID: 33013386 PMCID: PMC7506056 DOI: 10.3389/fphar.2020.544124] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 08/24/2020] [Indexed: 12/16/2022] Open
Abstract
Liver ischemia-reperfusion injury (IRI) is a common clinical event with high morbidity in patients undergoing complex liver surgery or having abdominal trauma. Inflammatory and oxidative stress responses are the main contributing factors in liver IRI. The iridoid glucoside aucubin (AU) has good anti-inflammatory and antioxidative effects; however, there are no relevant reports on the protective effect of glucosides on hepatic IRI. The purpose of this study was to determine whether AU pretreatment could prevent liver IRI and to explore the mechanism. Sprague–Dawley rats were randomly divided into five groups. The sham operation and IRI control groups were given intraperitoneal injections of normal saline, while the AU low-dose (AU-L) group, AU medium-dose (AU-M) group, and AU high-dose (AU-H) group were given intraperitoneal injections of AU at doses of 1, 5, and 10 mg/kg/day, respectively. After 10 d, liver IRI (70% liver ischemia for 1 h, reperfusion for 6 h) was surgically established in all groups except the sham group. Our results confirmed that liver injury was significantly aggravated after hepatic ischemia-reperfusion. AU alleviated the increase of transaminase and pathological changes induced by ischemia-reperfusion and improved liver damage. AU could also ameliorate the inflammatory and oxidative stress responses induced by ischemia-reperfusion and reduced expression of high mobility group protein (HMG)B1, receptor for advanced glycation end-products (RAGE), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and reactive oxygen species (ROS). Moreover, AU reduced ischemia-reperfusion-induced mitochondrial dysfunction and cells apoptosis, increased peroxisome proliferator-activated receptor γ coactivator (PGC)-1α and uncoupling (UCP)2 protein expression, and reduced caspase-3, cleaved caspase-3, and Cytochrome P450 proteins (CYP) expression. To determine expression levels of the Toll-like receptor (TLR)-4/nuclear factor-κB (NF-κB) pathway-related proteins in vitro and in vivo, we also measured TLR-4, myeloid differentiation factor88 (MyD88), NF-κB P65, p-P65, I-kappa-B-alpha (IκB-α), and p-IκB-α levels. The results showed that AU effectively inhibited activation of the TLR-4/NF-κB signaling pathway. In conclusion, we showed for the first time a hepatoprotective effect for AU in liver IRI, which acted by inhibiting the HMGB1/TLR-4/NF-κB signaling pathway, oxidative stress, and apoptosis. Pretreatment with AU may be a promising strategy for preventing liver IRI.

Abstract
Neovascularization in the retina is common pathophysiology of diabetic retinal microvasculopathy and exudative macular degeneration. Our study assessed the inhibitory activity of an ethanol-based extract of Aucuba japonica (AJE) on abnormal angiogenesis in the retina with a hyperoxia-induced neovascular retinopathy model. The inhibitory effects of aucubin, quercetin, and kaempferol, bioactive compounds, from A. japonica, on retinal vascular hyperpermeability were also examined. On the 7th postnatal day (P7), the C57BL/6 pups were exposed to a hyperoxic environment with 75% oxygen to develop the experimental angiogenesis in retinas. On the 12th postnatal day (P12), the pups were then returned to the normal atmospheric pressure of oxygen. From P12 to P16, the administration was intraperitoneal. The dose per day was 250 mg per kg weight. Retinal neovascularization was measured with retinal flat mounts prepared on P17. We also measured the vascular leakage mediated by the vascular endothelial growth factor (VEGF) in retinas. Mice treated with AJE had markedly smaller neovascular lesions, in comparison with vehicle-administered mice. AJE downregulated the expression of both VEGF protein and mRNA. In addition, aucubin, quercetin, and kaempferol ameliorated VEGF-induced retinal vascular leakage. The results of our study suggest that AJE is a potent antiangiogenic substance. AJE could also serve as a therapeutic agent for abnormal growth of vessels in the retina in patients with ischemic retinopathy. The bioactive compounds of AJE may be responsible for its antiangiogenic abilities.

Abstract
The β-glucan H6PC20 (Mw: 2390 kDa) and α-heteropolysaccharide HPB-3 (Mw: 15 kDa) were purified from the fruiting body of Hericium erinaceus according to the previous methods. Their gastroprotective activities and corresponding structure-activity relationship were studied in the ethanol-induced gastric ulcer model of rats. After intragastric administrated with H6PC20 and HPB-3 for 14 days, macroscopic and histological evaluation of gastric mucosa was improved significantly. The defense and repair factors (EGF, bFGF and PGE2) were increased, meanwhile, the inflammatory cytokines (IL-1β and TNF-α) and MDA were reduced. These results indicated that H6PC20 and HPB-3 presented gastroprotective activities with the mechanism of activating repair and defense system, decreasing the inflammatory response and alleviating the oxidative injury. Furthermore, the structure-activity relationship showed that the macromolecular β-glucan was better for repair and defense system, while the low weight molecular α-heteropolysaccharide focused on the anti-inflammatory effect. The polysaccharides purified from H. erinaceus can be developed as a potential gastroprotective ingredient for applications in pharmaceutical field.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) cause gastric mucosal damage and gastric ulceration. Among the most commonly used NSAIDs, indomethacin upregulates mucosal tumor necrosis factor-α, which activates nuclear factor-kappa B (NF-κB), and mitogen-activated protein kinases (MAPK) to induce various pro-inflammatory mediators. Polydeoxyribonucleotide (PDRN) is an adenosine A2A receptor agonist that exerts anti-inflammatory effects. In this study, we evaluated the efficacy of PDRN in the initial treatment of gastropathy against that of ecabet sodium and irsoglandin maleate, which are commonly used medications. The rats were administrated indomethacin once a day for 7 days after 24 h of fasting to induce gastropathy. Rats in the drug-treated groups were orally administrated 500 μl of distilled water containing the drug once daily for 7 days 1 h after indomethacin administration. Indomethacin administration caused mucosal damage and increased pro-inflammatory cytokine release. Both NF-κB and MAPK cascade factors were increased by indomethacin administration. PDRN therapy more potently suppressed the expressions of NF-κB and MAPK cascade factors compared to other drugs. The expression of cyclic adenosine-3',5'-monophosphate was also increased by PDRN treatment in the indomethacin-induced gastropathy rats. These changes led to a reduction in pro-inflammatory cytokines and apoptotic factors, which ultimately promote recovery of damaged gastric tissue. Therefore, PDRN may serve as a new therapeutic option in the initial treatment of NSAIDs-induced gastropathy.

Abstract
The aim of this study was to study the preventive effects of polyphenols extracted from Liubao Insect tea on gastric injury. The content of Liubao Insect tea polyphenols (LITP) was 72.36% by ion precipitation extraction method. HCl/ethanol-induced gastric injury in mice led to increased gastric juice volume and decreased pH. LITP increased the gastric juice pH value and reduced the gastric juice volume at slightly lower quantities than ranitidine. Visual observation of gastric tissue showed that LITP could effectively reduce the area of gastric injury, and higher concentrations of LITP had a greater effect. Pathological observation also confirmed that LITP can reduce the cell damage and inflammatory effects, and play a role in preventing gastric injury. Serum cytokine assays showed that LITP could reduce the levels of IL-6 (interleukin 6), TNF-α (tumor necrosis factor alpha) and IFN-γ (interferon gamma) induced by gastric injury, and the effects of higher concentration of LITP were similar to those of ranitidine. The results showed that LITP could increase SOD (superoxide dismutase) and GSH (glutathione) levels; decrease MDA (malondialdehyde) and MPO (myeloperoxidase) levels; up-regulate the expression of Cu/Zn-SOD (cuprozinc-superoxide dismutase), Mn-SOD (manganese superoxide dismutase), CAT (catalase), nNOS (neuronal nitric oxide synthase), eNOS (endothelial nitric oxide synthase); and down-regulate the expression of iNOS (inducible nitric oxide synthase), COX-2 (cyclooxygenase-2), TNF-α, and IL-1β (interleukin-1 beta) in mice with gastric injury, thus inhibiting gastric injury. We demonstrate that LITP is an active substance which could prevent gastric injury in experimental animals. With the increase of LITP concentration, its effects on preventing gastric injury were stronger and similar to those of ranitidine. The aim of this study was to study the preventive effects of polyphenols extracted from Liubao Insect tea on gastric injury.![]()

Abstract
Background Korean Red Ginseng is known to exhibit immune-enhancing and anti-inflammatory properties. The immune-enhancing effects of the nonsaponin fraction (NSF) of Korean Red Ginseng have been studied in many reports. However, the gastroprotective effect of this fraction is not fully understood. In this study, we demonstrate the activities of NSF for gastrointestinal protection and its related critical factor. Methods The in vitro and in vivo regulatory functions of NSF on cyclooxygenase-1 (COX-1) messenger RNA and protein levels were examined by reverse transcription polymerase chain reaction and immunoblotting analyses. Gastroprotective effects of NSF were investigated by histological score, gastric juice pH, and myeloperoxidase activity on indomethacin-induced, cold stress-induced, and acetylsalicylic acid-induced gastritis and dextran sulfate sodium-induced colitis in in vivo mouse models. Results NSF did not show cytotoxicity, and it increased COX-1 messenger RNA expression and protein levels in RAW264.7 cells. This upregulation was also observed in colitis and gastritis in vivo models. In addition, NSF treatment in mice ameliorated the symptoms of gastrointestinal inflammation, including histological score, colon length, gastric juice pH, gastric wall thickness, and myeloperoxidase activity. Conclusion These results suggest that NSF has gastroprotective effects on gastritis and colitis in in vivo mouse models through COX-1 upregulation.

Abstract
Aucubin (AUB), which is extracted from Eucommia ulmoides Oliver seeds, has been found to possess anti-inflammatory and antiapoptotic properties. Recent studies have indicated that inflammation, oxidative stress, and apoptosis are involved in the pathophysiology of lipopolysaccharide (LPS)-induced cardiac dysfunction. Our study aimed to investigate the effect of AUB on LPS-induced acute cardiac injury. Male C57BL/6 mice were injected with LPS (one 6 mg/kg injection) to induce cardiac dysfunction without or with AUB pretreatment (20 or 80 mg/kg per day) for 1 week. We found that AUB ameliorated cardiac dysfunction, inflammation, oxidative stress, and apoptosis induced by LPS stimulation. Mechanistically, AUB inhibited LPS-induced oxidative stress by decreasing reactive oxygen species and thioredoxin interaction protein (TXNIP) levels. Moreover, AUB suppressed LPS-induced inflammation and apoptosis by reducing nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3)/apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC)/caspase-1 inflammasome formation. Overexpression of NLRP3 in cardiomyocytes attenuated the protective effects of AUB. Interestingly, NLRP3 deficiency ameliorated cardiac function and reduced the inflammatory response and oxidative stress after LPS insult in mice, whereas AUB could not further prevent LPS-induced cardiac dysfunction in NLRP3-deficient mice. In summary, AUB exerts a protective effect against LPS-induced inflammation, oxidative stress, and apoptosis in vivo and in vitro by regulating the TXNIP pathway and inactivating the NLRP3/ASC/caspase-1 inflammasome. Hence, AUB may be a promising agent against LPS-induced cardiac dysfunction. SIGNIFICANCE STATEMENT: Aucubin exerts a protective effect against lipopolysaccharide-induced cardiac dysfunction by regulating nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 inflammasome.

Abstract
Prunus cerasus (P. cerasus) is an alternative-medicine used traditionally for amelioration of chronic-ailments marked by elevation in oxidative-stress like neuropathy. The oxidative-stress control was reported to ameliorate the inflammatory-process. This study aimed to phytochemically-investigate P. cerasus most-active phytochemicals utilizing in-vivo biological models to explore their gastroprotective, anti-inflammatory, and antinociceptive potentials and their possible mechanisms of action. Sonication with EtAc was used to extract P. cerasus fruit (Scf), and seed (Scs). The phytochemical-investigation of Scf was performed by RP-HPLC, while that of Scs was explored utilizing GC-FID. A bio-guided-fraction and isolation method was done utilizing column-chromatography, and have shown that cyanidin-3-glucoside (Cy3G) was the most-active constituent in Scf, while linoleic-acid (LA) was the most-active constituent in Scs. Scf, Scs, Cy3G, and LA significantly (p ˂ 0.05) protected the gastric-mucosa against HCl/EtOH-induced gastric-lesions. Scs (200 mg/kg) has shown the most gastroprotective-potentials, and had comparable-results to ranitidine (50 mg/kg). Scf, Scs, Cy3G, and LA have shown significant anti-inflammatory and antinociceptive potentials against carrageenan induced-edema and nociceptive-pain, respectively, where Scs (200 mg/kg) has shown the most anti-inflammatory and antinociceptive potentials, and had comparable results to ibuprofen (100 mg/kg). Scf, Scs, Cy3G, and LA have counter-acted carrageenan-induced oxidative-stress markers, with increased serum-catalase and reduced-glutathione levels, and decreased lipid-peroxidation. Histopathological-studies demonstrated gastroprotective potentials, regeneration and improvement of the spleen-structural architecture when treated with highest doses of Scs and Scf. The reduction of the pro-inflammatory TNF-alpha and IL-6, and elevation the anti-inflammatory factor IL-10 levels, spleen regenerative-capacity and oxidative-stress amelioration might be the main-mechanism responsible for P. cerasus anti-inflammatory potentials. P. cerasus appears to aid in ameliorating the inflammatory process, and reducing pain-thresholds while preserving the stomach.

Abstract
The Moringa plant (Moringa oleifera) is known for its potential medicinal properties and health benefits in addition to its high nutritional value. The current study aimed to investigate the antiulcer effect of moringa leaves and its aqueous extract on pro-inflammatory cytokines and inflammatory mediators in ulcerative rats. Rats were treated with either moringa leaves (10%) or moringa extract (300 mg/kg body weight) for 4 weeks then treated with a single dose of aspirin to induce gastric ulcer. Moringa leaves and its extract markedly reduced ulcer index, gastric volume and total acidity. Both treatments induced a significant increase in gastric mucosal mucin content and plasma NO level associated with significant decrease in plasma TNFα. Moringa leaves and its extract prompted down-regulation of TNFα, TGFβ1 and COX2 genes expression by 2.7, 3.5, and 8.4 fold-change for moringa leaves and 2.7, and 2.3, 4.1 fold-change for moringa extract, respectively. Moringa leaves and extract treatments altered the COX-1 gene expression levels to near normal values. This study confirms the gastro-protective influence of moringa leaves and its extract on aspirin-induced ulcer in rats as manifested by its significant reduction in inflammatory cytokines and normalization of gastric mucosal mucin and NO level. Overall, moringa leaves powder is more efficient as antiulcer agent than moringa extract.

Abstract
BACKGROUND Silkworm pupae are a traditional Chinese food, rich in various saturated and unsaturated fatty acids. Unsaturated fatty acids have a certain protective effect against oxidative damage. The present study used an animal model to determine the protective effect of silkworm pupa oil on hydrochloric acid / ethanol-induced gastric ulcer. RESULTS Silkworm pupa oil is rich in unsaturated fatty acids, including palmitoleic acid 63.4 g kg-1 , oleic acid 249.1 g kg-1 , linoleic acid 47.0 g kg-1 , and linolenic acid 337.8 g kg-1 , whereas its unsaturated fatty acid content is 700 g kg-1 . Compared to a gastric ulcer control group, high and low doses of pupa oil reduced gastric ulcer area and gastric secretion, whereas gastric pH increased. It also increased serum antioxidant superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) levels, somatostatin (SST), and vasoactive intestinal peptide (VIP) levels, and reduced serum interleukin-6 (IL-6), interleukin-12 (IL-12), tumor necrosis factor (TNF-α), and interferon-γ (IFN-γ), motilin (MTL), and gastrin (GT) levels. RT-qPCR and western blot analyses indicated that silkworm pupa oil significantly increased CAT, GSH-Px, epidermal growth factor (EGF), Epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), Cu/Zn-SOD, Mn-SOD, and NF-kappa-B inhibitor-α (IκB-α) expression and lowered nuclear factor-kappa B (NF-κB), B-cell lymphoma-2 (Bcl-2), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) expression. CONCLUSION Silkworm pupa oil treatment reduced oxidative damage and inflammation in mice, and high-dose silkworm pupa oil was superior to low-dose silkworm pupa oil, following ranitidine. © 2018 Society of Chemical Industry.

Abstract
Aucubin (AUC) is a major bioactive ingredient in Eucommia ulmoides, Plantain asiatica, and Aucuba japonica, and has been shown to exert anti-inflammatory, antioxidative, and neuroprotective effects. We explore the neuroprotective effects of AUC in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced parkinsonian mice. Mice were administered MPTP (30 mg/kg) daily for 5 days, followed by treatment with AUC for 7 days. Measurement of dopamine levels was performed by high-performance liquid chromatography and tyrosine hydroxylase expression was assessed by western blot. Our results showed that AUC treatment improved mobility in the pole descent test and the traction test, and reduced the loss of dopaminergic neurons in MPTP-induced parkinsonian mice. AUC treatment rescued the decreased dopamine and tyrosine hydroxylase levels in the striatum of parkinsonian mice. Furthermore, AUC treatment reduced both microglia and astrocyte activation in the substantia nigra of parkinsonian mice. These findings suggest that AUC exerts neuroprotective effects, in part by reducing inflammation and preserving dopaminergic neurons. Possible protection mechanisms involved in MPTP-induced parkinsonian mice need to be clarified further.

Abstract
PURPOSE Gastritis is found to be one of the most common gastrointestinal diseases worldwide. However, current therapeutic agents cause side effects, interaction, and recurrence. Allantoin has anti-inflammatory and wound healing properties. In this study, the therapeutic effect of allantoin has been assessed on the histopathological indices and gastric mucosal barrier of male rats. METHODS Male rats were equally divided into control, ethanol-induced gastritis, and allantoin groups. The therapeutic groups consisted of gastritis plus 12.5 mg/kg allantoin, gastritis plus 25 mg/kg allantoin, and gastritis plus 50 mg/kg allantoin groups. After 5 days of allantoin administration, the rats were sacrificed and a part of their gastric tissue was maintained at -70 °C for prostaglandin E2 (PGE2) and non-protein sulfhydryl (NP-SH) measurements. Another part was stained with hematoxylin and eosin and Masson's trichrome. RESULTS We found that Allantoin increased parietal and mucosal cell counts and mucosal thickness after gastritis induction. In addition, the number of leukocytes and vessels decreased in both of the mucosal and the submucosal layers. Allatoin improved gastric ulcer in all treatment groups. Gastric levels of PGE2 and NP-SH increased after allantoin treatment. CONCLUSION This study indicated that allantoin had a considerable effect on gastritis treatment, which seems to result from the reinforcement of gastric mucosal barrier.

Abstract
Acrostichum aureum Linn., a medicinal pteridophyte growing in mangrove forests and coastal regions of tropical and subtropical areas worldwide, has been proved to possess various biological effects. However, the protective effect of Acrostichum aureum Linn. against gastric ulcer still remains unidentified. Therefore, the gastroprotective effect of the water extract of Acrostichum aureum Linn. (WEAC) was investigated in ethanol-induced gastric injury model. According to our results, pretreatment with WEAC (100, 200, and 400 mg/kg) could dramatically decrease the ulcer areas and ameliorate the pathological damage induced by alcohol in rat's gastric tissues. In addition, WEAC administration prevented the stomach from oxidative damage via markedly increasing the levels of glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and decreasing the malondialdehyde (MDA). Besides, WEAC pretreatment alleviated inflammatory infiltration by reducing the secretion of proinflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) as well as decreasing the protein expressions of phosphorylation of IκBα and p65. Taken together, WEAC exerted potential therapeutic efficacy for gastric ulceration, and this may be involved in the suppression of oxidative stress and inflammatory response.

Abstract
Dry eye disease is affected by a broad range of causes such as age, lifestyle, environment, medication and autoimmune diseases. These causes induce tear instability that activates immune cells and promotes expression of inflammatory molecules. In this study, we investigated the therapeutic effects of an ethanolic extract of Aucuba japonica (AJE) and its bioactive compound, aucubin, on dry eye disease. The human corneal cells were exposed to desiccation stress induced by exposing cells to air, so that viability was decreased. On the other hand, pre-treatment of AJE and aucubin restored cell survival rate depending on the dose under the dry condition. This result was confirmed again by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. The mRNA expression of inflammatory molecules was reduced by the pretreatment of AJE and aucubin under the dry state. The therapeutic effects of AJE and aucubin were examined in the animal model for dry eye induced by unilateral excision of the exorbital lacrimal gland. Declined tear volumes and corneal irregularity in the dry eye group were fully recovered by the administration of AJE and aucubin. The apoptotic cells on the cornea were also decreased by AJE and aucubin. Therefore, this study suggests that administration of AJE can be a novel therapeutic for dry eye disease and that the pharmacological activities of AJE may be in part due to its bioactive compound, aucubin.

Potential Gastroprotective Activity of Rice Bran ( Oryza sativa L.) Extracted by Ionic Liquid-Microwave-Assisted Extraction against Ethanol-Induced Acute Gastric Ulcers in Rat Model. Sci Pharm 2018; 86:scipharm86030035. [PMID: 30205486 DOI: 10.3390/scipharm86030035] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 08/28/2018] [Accepted: 08/29/2018] [Indexed: 12/15/2022] Open
Abstract
The presence of gamma-oryzanol in rice bran oil can be 10⁻20-fold higher than tocopherol and tocotrienol. Gamma-oryzanol has various pharmacological properties. The objective of this study was to evaluate the effectiveness of rice bran extract as a gastroprotective in reducing lesions in ethanol-induced acute gastric ulcer models in rat, using the ionic liquid-microwave-assisted extraction (IL-MAE) method. Rice bran extract was obtained using the IL-MAE method with ionic liquid (IL), 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM]BF₄ (concentration 0.7 M), and a ratio of solid/liquid of 15 g/mL, 15 min extraction time, and 10% microwave power. The rats were pretreated with rice bran extract at different doses (100, 200, and 400 mg/kg body weight; BW) for seven days and subsequently exposed to acute gastric lesions induced by 80% ethanol. Omeprazole (36 mg/kg BW) was used as a standard anti-ulcer drug. The ulcer index, gastric juice acidity, and mucus levels were measured to assess the degree of gastroprotection. The results showed that the oral administration of rice bran extract at a dose of 400 mg/kg BW significantly inhibited the development of ulcer formation by 66.75% and reduced gastric acid levels. Moreover, gamma oryzanol and omeprazole protected the gastric mucosa from ethanol-induced gastric lesions by increasing the level of gastric mucus. Rice bran extract is effective as a gastroprotective therapy sourced from natural ingredients in treating the incidence of gastric ulcers. Most likely, this is related to gamma oryzanol as a bioactive compound contained in rice bran (Oryza sativa L.).

Mol Med Rep 2018; 18:3791-3799. [PMID: 30106096 PMCID: PMC6131224 DOI: 10.3892/mmr.2018.9352] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Accepted: 04/09/2018] [Indexed: 12/13/2022] Open
Abstract
Ethanol‑induced diseases of the gastric mucosa are the most common and refractory diseases of gastrointestinal system in clinic, and are mediated by oxidative stress and apoptosis pathways. Theaflavins (TFs) are considered to be antioxidants. The present study aimed to determine the molecular mechanism underlying the ability of TFs to attenuate ethanol‑induced oxidative stress and apoptosis in GES‑1 gastric mucosa epithelial cells. A Cell Counting Kit‑8 (CCK‑8) assay was performed to investigate the cell viability of GES‑1 cells following administration of ethanol (0.5 mol/l) and subsequent treatment with TFs (20, 40 and 80 µg/ml) for specific time intervals. A carboxyfluorescein diacetate succinimidyl ester assay was used to measure proliferation and further investigate the results of the CCK‑8 assay. Flow cytometry was performed to measure reactive oxygen species (ROS) levels and the apoptosis rates of GES‑1 cells. Furthermore, levels of oxidative stress‑associated factors, including malondialdehyde, superoxide dismutase and glutathione, were investigated using commercial kits. Reverse transcription‑quantitative polymerase chain reaction and western blot assays were performed to determine the expression levels of apoptosis‑associated factors, as well as the phosphorylation levels of extracellular signal‑regulated kinase (ERK), c‑Jun N‑terminal kinase (JNK) and p38 kinase (p38). The results of the present study demonstrated that treatment with ethanol inhibited GES‑1 cell proliferation, and enhanced ROS levels and apoptosis rates, potentially via downregulation of B‑cell lymphoma‑2 (Bcl‑2) expression and upregulation of Bcl‑2‑associated X and caspase‑3 expression levels, as well as enhancing the phosphorylation levels of ERK, JNK and p38. However, treatment with TFs was revealed to attenuate the effects of ethanol administration on GES‑1 cells in a dose‑dependent manner. In conclusion, TFs may attenuate ethanol‑induced oxidative stress and apoptosis in gastric mucosa epithelial cells via downregulation of various mitogen‑activated protein kinase pathways.
